I am using WordPress MU 2.9.2. I had been using WordPress prior to this but I needed a multiblog environment and felt the single portal would be better than having to log into multiple blogs to make changes.
I made a switch to a new server when I did this change so I have a fully fresh install. I am using vhosting and have setup a "*" subdomain through cpanel.
Everything seems to be working except I cannot use images that are uploaded to any of the blogs I've setup. They get uploaded to the server, but show up as broken images. It seems like this is a problem with the redirect.
I have checked my .htaccess file and I believe it is correct. I know of 2 other MU accounts on this server that aren't having this problem so it seems the server doesn't have a problem with the redirects.
This is the content of the .htaccess file
